For ib_copy_from_user(), the length of udata may not be the same as that
of cmd. For ib_copy_to_user(), the length of udata may not be the same as
that of resp. So limit the length to prevent out-of-bounds read and write
operations from ib_copy_from_user() and ib_copy_to_user().

Whether to enable the these features should better depend on the enable
flags, not the value of related fields.

The high 6 bits of traffic class in GRH is DSCP (Differentiated Services
Codepoint), the driver should shift it before the hardware gets it when
using RoCEv2.

Only the low 12 bits of vlan_id is valid, and service level has been filled
in Address Vector. So there is no need to fill sl in vlan_id in Address
Vector.

According to the RoCE v1 specification, the sl (service level) 0-7 are
mapped directly to priorities 0-7 respectively, sl 8-15 are reserved. The
driver should verify whether the value of sl is larger than 7, if so, an
exception should be returned.

Can any of these warn_on's be triggered by user space? That would not
be OK

Hi Jason,
Thanks for your comments, I understand that error that can be triggered by
userspace shouldn't use WARN_ON(). So I shouldn't use WARN_ON() in
hns_roce_v2_set_path().
As for the error in process of post_send, you suggested me to warn_on if
a kernel user try to pass in an illegal opcode. So I guess I should use
WARN_ON() too in sl's check when filling a UD WQE. Am I right?

Userspace should not be able to trigger warn_on
Bad kernel ULPs are OK to trigger warn_on

As the qp access right is checked and setted in common function
hns_roce_v2_set_opt_fields(), there is no need to set again for a special
case INIT2INIT.

From: Weihang Li @ 2020-12-04 10:40 UTC (permalink / raw)
To: dledford, jgg; +Cc: leon, linux-rdma, linuxarm
From: Yixian Liu <liuyixian@huawei.com>
There is no need to get queue number repeatly for different queues from an
AEQE entity, as they are the same. Furthermore, redefine the AEQE structure
to make the codes more readable.
In addition, HNS_ROCE_EVENT_TYPE_CEQ_OVERFLOW is removed because the
hardware never reports this event.
